FREDERICK HEIM, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO WILLIAM ROBBINS, OF SAME PLACE.

HOSE-BRIDGE.

SPECIFICATION forming part of Letters Patent No. 336,482, dated February 16, 1886. Application filed July 8, 1885. Serial No. 171,022. (N model.)

.T 0 all whom it may concern.-

Be it known that I, FREDERICK HEIM, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Hose-Bridges, which improvement is fully set forth in the following specification and accompanying drawings, in which- IO Figure 1 represents a side elevation of a hose-bridge embodying my invention. Fig. 2 represents a side elevation of a portion thereof on an enlarged scale. Fig. 3 represents a vertical section in line mm, Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

My invention relates to improvements in an elevated hose-bridge; and it consists of the construction and connection of parts whereby the bridge may be laid flat on the ground, and the hose placed thereon, raised, and then supported at an elevation over cars and other vehicles, and other advantages are presented, as will be hereinafter set forth.

2 Referring to the drawings, A represents a head, which is supported on legs B, the latter being hinged or pivoted to the head in such manner that they may be spread and folded somewhat after the manner of atripod, the

legs, however, being adapted to be spread out flat on the ground or pavement. The head is grooved on its upper face, the grooves O in the present case being three in number, to which, however, I do not limit myself, said head being formed of wood, and having on its under face a metallic plate, A, with which one half of each knuckle of a hinge or pivot of the legs is formed, although, if desired, the head may be made of metal cast with said knuckles. The grooves O are designed to receive the hose to be elevated, and in order to prevent abrupt-mess in the bends of the hose at the ends of the head the bases of the grooves are made convex, so as to curve in an upward direction the portion of the hose which rests upon the head.

It will be seen that in case of fire the legs spread flat on opposite sides of car-tracks or of a street and the hose run or thrown on the head of one bridge to the other over the track or street. The bridges are then raised by their legs and set in position, thus elevating the hose in such manner that cars and other vehicles may pass under the elevated portion thereof, the stopping of the cars, &c., or cutting of the hose by the cars riding over the same being thereby avoided. The bridges remain firmly in position and are not liable to slip, as is occasioned in the class of bridges which rest on car-tracks or directly on the streets.

The bottoms of the legs are provided with spurs, so as to take firm hold of the ground or pavement, and, as the legs may be spread more or less, the height of the head of the bridge may be readily adjusted.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An elevated hose-bridge having ahead, A, in combination with the plate A, having lugs on the under side thereof, and legs B, pivoted in said lugs, substantially as described.

2. An elevated hose-bridge having the head A, formed with concave grooves having con vex bases, plate A, secured to said head, and legs B, pivoted to the said plate, substantially as described.

FREDERICK HEIM.
